1. An external component arrangement for a cochlear implant system for a patient, the cochlear implant system further including an implanted portion having implanted components including an implant coil, the external component arrangement comprising:
- an external housing, the entire external housing configured for placement external to the skin of the patient, the external housing containing;
i. a signal processing stage enclosed within the external housing, the signal processing stage for generating an electrical signal for the implanted portion of the system, andii. an external coil enclosed within the external housing, the external coil for transmitting the electrical signal transcutaneously through the skin of the patient to the implant coil of the implanted portion; and
an impact absorber containing the external housing wherein the impact absorber shields system components within the external housing and underlying implanted components from a mechanical impact to the impact absorber which produces an associated impact energy, wherein the impact absorber includes reinforcing ribs which distribute the impact energy towards an outer perimeter of the external component arrangement.

Abstract
An external component housing is described for a cochlear implant system. A signal processing stage is contained within the housing for generating an electrical signal for an implanted portion of the system. An external coil is also within the housing for transmitting the electrical signal transcutaneously through the skin of a patient to the implanted portion. An impact absorber shields the system components from the impact energy associated with a mechanical impact to the housing.
